Diffing gcc-3_3{,-rhl}-branch, I think just 2003-05-16 Jakub Jelinek <jakub@redhat.com> * config/ia64/unwind-ia64.c (uw_update_reg_address): Handle .save XX, r0. might be the difference which matters. This patch is on the trunk, gcc-3_3-rhl-branch and gcc-3_2-rhl8-branch, but not on gcc-3_3-branch. Might ask Mark if he allows that for 3.3.2... Certainly, without that not just backtrace, but lots of other things (like NPTL) don't work properly. Jakub
